MININGQWACHINE.

SPECIFICATIGII forming part of Letters Patent No.307,514=, dated November 4, 1884.

Application filed February 1G. 1883. (No model.)

To @ZZ whom, tm/ay concern.-

Beit known that I, BENHARD Yoon, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful In1- provernent in llIining-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speciiiea'tion.

My invention relates to an engine for use in a inine for channeling and undercutting coal.

The scope ofthe invention is set forthin the clainis.

Figure l is a plan of tlieniaehine. Fig. 2 is a transverse section at 2 2, Fig. 1. Fig. 3 is a detail side view. Fig. Li is a detail rear view. Fig. 5 is an enlarged detail side view illustrating the construction ofthe brake. Fig.

` 6 is a detail vertical section (enlarged) showing the connection` of the brake mechanism and one of the axles. Fig. 7 is an enlarged vertical section showing the connection between the niain frame and the engine-supporting frame, the latter being shown in its working posit-ion, the plane of the section being indicated at 7 S, Fig. 8; and Fig. S is a detail section on saine plane, showing the enginesupporting frame in its elevated position for convenience in ino'ving the :machine from place to place. Fig. 9 is an enlarged detail showing one of the hanger-arms with the trunnion which supports the cylinders upon 011e side,

' the construction allowing the oscillatory inovenient of the engine cylinders in a vertical plane. Fig. 10 is an enlarged transverse section at 10 10, Fig. 1. Fig. 1l is an enlarged transverse section at 11 11, Fig. 1. Fig. 12 is an enlarged detail top view of the gl'iidei'raine ofthe piston-rods, part being in section. The scale of the following figures is larger than that of Figs. 1, 2, 3, and 4. Fig. 13 is aplan ofthe engine, part being Iin section. Fig. 14 is a rear view of the engine, part of one of the heads being broken away. Fig. 15 is a vertical section at 15 15, Fig. 13, showing a part front view of the engine. Fig. 1G is a transverse section at 16 16, Fig. 20. Fig. 17 is a transverse section at 17 17, Fig. 20. Fig. 18

Vis a side View of the two picks, and Fig. 19 is a top view of the same, illustrating the relative positions at the point of striking the coal, (in fact the picks do not strike simultaneously, 'but alternately, so that these gures do not show a possible position of the picks, because when passing each other they would be farther apart than shown, owing to the oblique relative positions of the Vpiston-rods.) Fig. 2O is a horizontal section at 20 20, Fig. 21. Fig. 21 is a vertical longitudinal section at 2l 21, Fig. 20. Fig. 22 is avertical longitndinal section at 22 22, Fig. 20. Fig. 23 isa transverse section at 23 23, Fig. 20. Fig. 2J.c is a transverse section at 21 24:, Fig.. 20.

A A are trackfrails, (see Fig. 2,) upon which the inachine is supported when at work by ineans of front wheels, B, and rear wheels, B. The wheels turn on arbors or axles C, fixed in theside bars D. The arbors C of wheels B are shown extending through the side bars, and secured by a nut, E, bearing against a thick washer orsleeve, F, that bears against the side ofthe side bar. The arbors of wheels B B forni the bearings upon which. hang hanger-arms Gv, to whose lower ends are connected the triangular brake-blocks H, which blocks serve to hold the machine in place when at work, acting as chocks to the wheels by insertion into the angles between the wheels and the track. The brake-blocks or chocks H are connected to the arins by studs I, thateX- tend through slots .l in the arms G, so as to allow the blocks to fall out of contact with the periphery of the wheels when it is desired to free the wheels for the movement of the inachine.

l are togglelinks, by which the brake` blocks upon each sideare connected toa hanger-lin'k, L, coinnion to both. I show the link L weighted so that its weight upon the toggle arins or links K may force the brake-blocks apart into the` space between the wheels and the rail. The upper end of the link Lis connected to the front end of the lever M. This lever is shown fulcruined upon the arbor C of wheel B. The rear end of the lever hasa longitudinal slot, M', that receives the pin N of a crank, N. The cranks N are at each end of a rock-shaft, O, that is turned in its bearings by a handle, l. XVhen the shaft O is so turned that the cranks N point downward,the rear end of the lever M is depressed and the brakes H are drawn upward from the rails A,

IOO

necting-studs-such as duplication of the studs and duplicationA or elongation of the slots.

The shaft O has bearings upon the cross-bar Q of the carriage-frame. The bar Qis forked at the ends Q', and the fork ends are jointed by pintle-pins D" to the forked rear end, D', of the side bars D. The construction is such that the side bars have independent longitudinal movement to allow the engine to be turned to swing the picks to the right or the left, while the forking of the ends ofthe bars gives stability to the frame, so as to preserve the verticality ofthe bars and integrity ofthe frame as a support for the engine. The fore ends of the side bars D are secured together by the bridge-bar R. The bar R is connected to the side bars by a vertically-descending pin, S, at each end. These pins S nt freely in sockets T in the side bars. The construction is such that the described longitudinal movement of the side bars is not interfered with. The pins S are drawn upward in the sockets T when the engine islifted in the frame preparatory to moving the machine from place to place. XVhen the pin S is raised in the socket, it may be held up by a traverse-pin, S', passing through the pin S and bearing upon the top of the socket T. (See Fig. S.) U are hanger-arms which depend from the bridgebar R. To the lower ends of the hangerarins are connected the side bars, V, on which the engine is supported. The connection between the side bars V and the hanger-arms is made by means of a screw-stud, V', and nut V. (See Fig. 9.) The construction is such that the engine can be oscillated upon the studs V' to raise or lower the picks. The side bars V are embraced by brackets V, (see Figs. 23 and 24,) extending from the sides of the engine-cylinders X and X', and the bars are secured to the brackets by bridleplates XV' and screws WV". The cylinders can be adjusted longitudinally upon the bars V,

` so as to balance them as may be desired upon the trunnion-pins V'.

Y is a bow-formed handle connected to the side bars V by sleeves Y', that are capable of sliding on said bars to adjust the position of the handle, which is fixed in position by setscrews Y The engine-cylinders are not parallel with each other, but are so inclined that the picks strike near the Same place upon the coal, (see Figs. 1, 13, 18, and 19,) the axes of the cylinders being farther apart at the rear end than at the front end. The pistons are seen at Z Z', kthe piston-rods at aand a'. The piston-rod c ofthe piston Z is set into the pist0n below the center of the piston, and the other piston-rod, a', is set in above the center of its piston Z', and as the pistons are on the saine level it will be seen that the pick b upon the rod a, will strike a point below the levelv of the point struck by the other drill-pick, b'.

The points of impingeinent ofthe picks have the same relative positions as described in the specication to my application for patent, Serial No. 77 ,780. In the said application the picks strike simultaneously, both tools being -on one head, attached to parallel piston-rods;

but in my present invention there is no attachment of one rod to the other to interfere with their independent longitudinal movement. The parts of the piston-rods outside the cylinders work in a guide-frame, c c', the same being made with an upper member, c, having two semi-cylindrical recesses, c2, and a lower member, c', of similar forni. The members are connected together by bolts d, and are secured to the cylinder-heads by brackets e, spanning the stuffing-boxes f. (See Figs. 1 and 13.)

To prevent the turning of the piston-rods, I secure in them a key, g, that works in groove L in the guide-frame, the grooves beingmade partly in each member c and c'. (See Figs. 1Q and 12.)

The two cylinders X X' are shown as cast in one piece; but this is not material.

To complete the machine, the following means for operating the engine are provided:

z' is the valve-chest, into which the conipressed air or steam enters at j, (or any other suitable point.) The slide-valves are actuated by la valve-engine. This has a cylinder, k, 1n which works a piston, Z.

IOO

This engine has ordinary steam or air ports and usual slide-valve, m, that is Worked by an eccentric, n, on the shaft o. The shaft o has a crank, p, passing through a journal-block, q, that works vertically in a yoke, r, that is upon the piston-rod s of the valve-engine, said rod s forming the valve-stem of the main engine.

vThe crank-shaft o carries at one end a fly- IIO x2 is the front valve-port of cylinder X', and y the rear valve-port of cylinder X'.

The valve-ports a' x x2 x each communicate with a passage, y, extending to the end of the cylinder, so that when either of these ports is in communication with the interior of the valve-chest the compressed air or steam, as

the case may be, runs throughvthe to the end of the cylinder-chamber.

To prevent the escape of the cushioning air through the passage g/ an upwardly-opening check-valve, e, is placed in the passage, which is opened by pressure from beneath `of air from the port w a, if-c., but which closes by gravity and prevents the escape of air from the end of the cylinder-chamber to said port. l are serewplugs, by which access is had to the valves I claiml. In a mining-machine, the combination, with an engine, of the sidebars having vertical sockets at their fore ends, pins adjustable in said sockets, each having holes to receive a transverse pin resting on the top of the socket, a transverse bridge-bar supported on said pins having depending bars, and side bars supporting the engine, having` studs journaled in the depending bars, as set forth.

2. In a mining-machine, the combination, with an engine, of the side bars having vertical sockets at their fore ends, transverse bar jointed to their rear ends, pins mounted in said sockets, transverse bridge-bar pivoted to the tops of the pins having depending bars,

and side bars secured to engine, having studs journaled in the depending bars, asset forth.

passage y l In a mining-machine, the combination, with an engine, ofthe side bars, D, having vertical sockets attheir fore ends, upwardly and downwardly extending rear ends, D, cross-bar Q, having upwardly and horizontally extending outer ends, Q, pins D, pivoting the ends of the side bars and cross-bar together, vertical pins S, mounted in the sockets, transverse bridge-bar It, having depending bars U, and engine side bars, V, having studs secured to the depending bars, as set forth.

4. In a mining-machine, the combination of two pistons working. in cylinders placed side Vby side with piston-rods above the center of one piston and below the center of the other' piston, the said rods carrying drill-picks, as set forth.

5. In a mining-machine, the combination of two cylinders and pick-rod-supporting frame mounted all on the same level, and having their passa-ges inclined toward each other from rear to forward ends, and pistons having pick-rods mounted one above and the other beneath the center of the pistons, as set forth.
